WINDOW-SCREEN.

' Specification of Letters Patent. Patented Sept. 10, 1918.

Application filed September 11, 1917. Serial No. 190,794.

To all w/wm it may concem: I i

Be it known that 1, Jon HENRY Form, a citizen of the United States, residing at Merrill, in the county of Plymouth and State of Iowa, have invented certain useful Improvements in Window-Screens, of which the following 'is a specification, reference being had therein to the accompanying drawing.

The invention relates to a screen and more particularly to the class of sliding-screens for windows.

The primary object of the invention is the provision of a screen of this character wherein the frames thereof are formed to allow the removal of the wire. mesh should the same become damaged and unfit for use, so that new wire mesh can be substituted.

' Another object of the invention is the provision of a screen of this character wherein the guides for slidably mounting the screen frames are novel in form to allow the easy application of said guides to the window frame and the removal thereof with the screen frames as a unit without necessity of skilled labor.

A further object of the invention is the provision of a screen of this character which will withstand climatic conditions so as to avoid the necessity of its removal during winter weather.

A still further object of the invention is the provision of a screen of this character which is simple in construction, thoroughly reliable and efficient in its purpose, strong, durable, readily and easily applied to a window and removed therefrom and inexpensive in manufacture.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a front elevation of a window with the screen constructed in accordance with the invention applied;

Fig. 2 is an enlarged sectlonal v1ew'-on the line 2--2 of Fig. 1;

i Fig. 3 is a sectional view on the line 33 a Fig. 1;

Fig. 4 is a fragmentary perspective view .of one of the screen frames;

Fig. 5 is a fragmentary perspective view of one ofthe guides; and

Fig. 6 1s a sectionalview on the line (i -6 ofFig. 4.

is of the ordinary well known construction having therein the usual sliding sashes and in this frame or casing is mounted the screen hereinafter fully described. I

The screen comprises a pair ,oflguides B and upper and lower sliding screen sections C and D, respectively, the and sections being hereinafter fully described.

The upper and lower screen sections C and D comprise a frame including U-shaped vertical side members 10, a top member 11 and bottom member 12, each of which is made from a strip of metal bent on itself to form channels, within which there is received the marginal edge' of a wire mesh fabric 13. The ends of the side members 10 are engaged in' the channels of the top and bottom members 11 and 12 at the extremities thereof while passed through all the members are staples 14 which secure the wire mesh fabric. 13 and also secure the members connected with each other, the staplesll being removable to permit the disengagement of the wire mesh fabric 13 from the members or the disengagement of the parts from each other.

Secured to the vertical guide beads or strips E for the window sashes at the outer side of the window frame are the screen guides B each'comprising a strip like plate 15 preferably made from metal and which is co-extensive with the vertical stretch of the sash bead or strip and is formed at intervals with suitable holes for the reception of fasteners 16 to detachably secure the plate 15 on the outer face of the bead or strip E and this plate 15 ,is bent on itself to provide at the inner side thereof spaced parallel closely arranged U-shaped portions 17 and 18 respectively which provide the channeled guideways for the upper and lower screen sections C and D for sliding movement thereof in the opening and closing of either of said sections.

On the bottom member 12 of the upper screen section C is secured an inverted substantially U-shaped meeting strip 19'which serves to close the gap between the upper and lower screen sections C and D when said sections have been adjusted in the guides B to a closed position in the window frame or casing and thereby prevent the exit, of flies or insects to the interior of an inclosure through the window frame.

On the bottom member 12 of the lower screen section D are hand holds 20 which permit the manual raising and lowering of said section as will be apparent. Mounted on both upper and lower sections C and D at proper points thereof are catches 21 which permit the fastening of the screen section's when in closed position.

The channeled portions 17 and 18 on the plates 15 which constitute the guides B possess slight resiliency was to frictionally engage the upper and lower screen sections C and D yet permit the sliding movement of said sections without undue binding action in the opening and closing thereof.

It is of course understood that the wire mesh fabric 1-3 may be secured in the members of the frames for the detachment of the wire mesh other than by the use of staples yet it is essential that the members be detachably connected to each other and also that the wire mesh be detachable from said members so that in event of dama e to the holder another wire mesh can be su stituted thereby increasing the longevity of the screen structure in the use thereof.

It will be understood that the screen structure is preferably made from metal so that climatic changes will not affect the same while in use, so that on the mounting of the screen structure within the window frame it can remain therein during summer and winter seasons.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood and therefore a more extended explanation has been omitted.

What is claimed is:

1. A window screen structure comprising a pair of guides each formed from a striplike plate having means for attachment to the guide strip for the sash of a window, each plate being bent on itself to form sub stantially U-shaped spaced parallel closely arranged guide portions atone side thereof, a pair of screen frames slidably engaged in the guide portions of said plates, and a U- shaped 'meeting strip secured to one of the frames to close the gap between the screen frames when in closed position within the window frame.

2. A window screen structure comprising a pair of guides each formed from a striplike plate having means for attachment to the guide strip for the sash of a window, each plate being ,bent on itself to form substantially U-shaped spaced parallel closely arranged guide portions at one side thereof, a pair of screen frames slidably enga ed in the guide portions of said plates, a U-s aped meeting strip secured to one of the frames to close the gap between the screen frames when in closed position within the window frame, each screen frame including U- shaped side, top and bottom members, and a wire mesh fabric having its marginal edge engaged in the members.

3. A window screen structure comprising a pair of guides each formed from a striplike plate having means for attachment to the guide strip for the sash of a window, each plate being bent on itself to form substantially U-shaped spaced parallel closely arranged guide portions at one side thereof, a pair of screen frames slidably engaged in the guide portions of said plates, a U-shaped meeting strip secured to one of the frames to close the gap between the screen frames when in closed position within the window frame, each screen frame including U-shaped side, top and bottom members, a wire mesh fabric having its marginal edge engaged in the members, and means for detachably con JOE HENRY POHL.
